In summary, data transmission method provided in an embodiment of the present invention, transmitted by detecting in the GTP-U packets that receive whether be predefined type data；If testing result be the GTP-U packets in transmit be predefined type data, the GTP-U packets are unsealed, the destination address of the data of the predefined type and the data of the predefined type is obtained；The data of the predefined type and the destination address are sent to information gateway, the payload of IP packets can be reduced by solving the addition IP packet header before small data, and the problem of reducing data transmission efficiency has reached the effect for improving data transmission efficiency.Embodiment two
Fig. 4 is referred to, the method flow diagram of the data transmission method provided it illustrates the embodiment of the present invention two, the data transmission method is method for transmitting uplink data, be can apply in EPS.The data transmission method, can include：
Step 401, gateway obtains the type of message in GTP-U packet headers；
The data that GTP-U packets are received on to eating dishes without rice or wine are obtained after carrying out GTP-U protocol encapsulations.If what is received on eating dishes without rice or wine is IP packets, the IP data envelopes can be dressed up GTP-U packets and be transmitted.If what is received on eating dishes without rice or wine is the data of the predefined type of non-IP packets, then the data of predefined type directly can be packaged into GTP-U packets to be transmitted, it is to avoid the problem of adding the reduction data transmission efficiency that IP packet header is caused before the data of predefined type.Wherein, the data of predefined type can be small data or other kinds of data, and the present embodiment is not construed as limiting.Small data can be the message that application program is produced, including status message, location message, heartbeat message and real-time messages etc.；Can also be SIP signalings, Push message and control message etc..
Before encapsulation GTP-U packets, because GTP-U packets are obtained by wireless access network element encapsulation, therefore, if what is transmitted in GTP-U packets is the data of predefined type, then wireless access network element is before the GTP-U packets are encapsulated, it is necessary first to receive the data of the predefined type of user equipment transmission.Specifically, user equipment can be detected to the data type of data, if it is the data of predefined type that testing result, which is data, the data of the predefined type are then sent to by wireless access network element by the idle message of optimization, wherein, the idle message of optimization is the improvement based on existing message, and the present embodiment is not repeated；If it is not the data of predefined type that testing result, which is data, wireless access network element is sent the data to by existing IP transmission paths.Specifically, the detection such as data type that UE can be specified according to the size of data, the quantity of data or application program data whether be predefined type data, the present embodiment is not to detecting that the method for data of predefined type is construed as limiting.
Preferably, the destination address of the data of predefined type can also be entered together with the data of the predefined type Row encapsulation, after gateway deblocking GTP-U packets, can send the data of the predefined type according to the destination address.
When encapsulating GTP-U packets, can be with the data of the predefined type of right and wrong IP packets due to what is transmitted in GTP-U packets, can also be IP packets, therefore, in order to be made a distinction to the data transmitted in GTP-U packets, the type of message in GTP-U packet headers can also be configured in advance.Such as, can be to the type of message in the GTP-U packet headers（Message Type) numerical value be configured, with identify transmitted in the GTP-U packets be predefined type data.Specifically, type of message in GTP-U packet headers defines 256 numerical value, any one numerical value then can be selected from 256 numerical value, such as 00000001, if what is then transmitted in GTP-U packets is the data of predefined type, the type of message in the GTP-U packet headers is then set to 00000001, with identify the GTP-U packets transmission be predefined type data.
It should be added that, if the gateway in the present embodiment is packet data gateway, the gateway that type of message can be by wireless access network element or between wireless access network element and packet data gateway is pre-set；If the gateway in the present embodiment is gateway, type of message is pre-set by wireless access network element.
If type of message is set by wireless access network element, no matter gateway is gateway or packet data gateway, can determine that what is transmitted in GTP-U packets is the data of predefined type according to type of message.If gateway is packet data gateway and wireless access network element is not provided with type of message, then gateway can be detected according to the Tunnel End Point Identifier of wireless access network element transmitted in the GTP-U packets that receive whether be predefined type data, if testing result be GTP-U packets in transmit be predefined type data, the type of message in GTP-U packet headers can be then configured, so that packet data gateway can determine that what is transmitted in GTP-U packets is the data of predefined type according to the type of message after setting.Method to set up to type of message refers to foregoing description, does not repeat herein.
